Abstract
The fate of heavy quarkonia states has been investigated in QCD at high temperature when the plasma has a small momentum space anisotropy within a quasi-particle model. A real time static potential has been obtained from a Hard thermal loop expression for the gluon self-energy, by employing the quasi-parton equilibrium distribution functions extracted from hot QCD equations of state of O ( g 5 ) and O ( g 6 ln ( 1 / g ) ) . Employing the potential, quarkonia melting has been studied. It is found that the equations of state and the momentum anisotropy cause significant modifications in the screening properties of the plasma.
